NASA: First planet outside the Milky Way galaxy...?
A black hole or neutron star that emits X-rays draws the gas from a neighbouring star. Astronomers have discovered evidence of a planet beyond the Milky Way. It will be the first planet discovered outside of the Milky Way if it is discovered to be a planet.
However, they were all discovered within the Milky Way galaxy, which is where we dwell. At Messier 51, NASA's Chandra X-ray Telescope detects signs for a new planet. The Milky Way galaxy is 28 million (2.8 billion) light-years away from us.
The brightness of X-rays originating from a type of space object known as X-ray Bright Binary was discovered to be low. In most cases, such objects contain a neutron star or a black hole that consumes gas from surrounding stars.
Near the X-ray binary stars, this is a one-of-a-kind method of estimating the brightness emitted by an object termed a light curve. There is a black hole or neutron star in this binary star. A neutron star is a decaying core of what was once the biggest star in the universe.
The distance between the planet's black hole or neutron star might be double the distance between Saturn and the Sun. When the technology used to successfully discover extrasolar planets in the Milky Way is extended to other galaxies, it becomes dysfunctional.

Due to the great distance, the amount of light reaching the telescope reduces. One reason why technology cannot function well is that there are too many materials in a limited space, as we can see from Earth.More evidence is needed to prove this, according to the researchers. The double star would take 70 years to return since the candidate planet's orbit is so enormous. As a result, no research can be done on it shortly.
Problems like peering too closely at objects and darkening them are not addressed by current optical or infrared telescopes and scientists continue to study planets outside the Milky Way. The findings were published in Nature Astronomy.
